OK, so I received a defective unit yet I still rate it 5 stars...WHY???Because this thing is awesome! First one I ordered was trashed during shipping... with the air port sticking out of a hole the box when it arrived. NO THANKS! I decided to return that one because I figured it was probably damaged somehow by the idiots also called UPS. Second one I bought was in better shape when it arrived, so I used that one. Like others said in their negative comments, it does pull air in to the rubber bleeder adapter, but so what. It still pulls plenty of fluid, and there is NO way any of that air is getting in the caliper. You would need a negative pressure in the lines for that to happen, and this thing is always pulling a vacuum when activated. I did have two other issues though, but again, it worked so well that it still gets 5 stars. First issue is that after using continually for about 10-15 minutes, it started spitting and sputtering from the exhaust and the vacuum stopped. I had to let it sit for a few minutes and then tried it again. It then worked for a minute or two and then started spitting and sputtering again. Was barely able to finish the second caliper because of this. NOW, this may be caused by water in my air line or maybe not... I do not know what the cause. After a few days I tried again and it worked fine. I do have a line drier installed but it may not be working well enough for a continuous compressor run. This thing pulls a pretty awesome vacuum at 120 psi, but obviously your compressor will have a harder time keeping up, as mine barely did. Second problem is that mine leaked brake fluid from the vacuum port on the lid while in use. Not sure if the fitting in the lid was not installed tightly, but it did leak fluid onto the lid when in use. I did not see a way to tighten the fitting, as I was unable to remove the lid to check the underside. Did not leak a ton, but in my opinion, it should not leak at all. SO... in the end, I returned it because of that. In spite of the leak and spitting/sputtering issues, I absolutely will buy another when I need it. This thing is hands down AWESOME, and easily allows a 1 man bleed job. The fluid pull is slow enough that you can lock on the handle and stand at the reservoir to keep it topped off. Add a little extra above the max fill line, and by the time you get back to the caliper to tighten the bleed screw, your reservoir is right where it needs to be - and the job is done. I bled all 4 calipers on a 2008 Mitsu Lancer with the spongiest brakes I ever felt, and the pedal is now ROCK SOLID!!! Thank you Capri Tools! Again, I will absolutely buy another... hopefully one that does not leak.

I was genuinely surprised at how well this vacuum bleeder worked. I installed a new master cylinder in my Tempest so I knew I was going to have to bleed the whole system again. I've always done the old-fashioned two-person brake bleed and it's always been slow, annoying, and you actually have to have a friend (something I'm terrible at doing). I looked at quite a few one-man bleeder systems, most of which seem pretty cheap, flimsy, and had hit-and-miss review scores. I didn't want to buy something that didn't work well enough only to have to do it the old-school way anyway. All the positive reviews on this unit just told me to buy it, try it, and be unnaturally optimistic.The unit arrived fully assembled and ready to rock-and-roll. The pneumatic quick-release fitting was already attached and it secured to the quick-release Milton fittings on my air hose just fine with no audible leaks. It's incredibly straightforward to use. Hook rubber hose and nipple up to the brake bleeder valve, crack it open, press the button on the vacuum and watch the fluid and air bubbles get pulled out of the system. It all drains into a very generously large reservoir; it will hold way more fluid than you'll reasonably pull from any brake system. All the parts seem to be good quality and I can see that it will likely last quite some time. The rubber/silicone hose may need to be replaced at some point but clear plastic hose is readily available at pretty much every hardware store. The hose that is on the unit isn't completely clear like I was expecting or accustomed to using during a bleed job. It's a translucent white color. You can still see through it fine but I'm used to completely clear vinyl-like hose. No big deal, it gets the job done just fine.The only thing that made using this vacuum system a bit awkward was judging when the air is actually purged. The fluid comes out of the bleeder valve much faster than when using the old-school method that it's sometimes hard to tell whether there are air bubbles or whether it's just fluid rushing by so quickly that it LOOKS like air. Regardless, I decided each wheel was done when I stopped seeing BIG bubbles for a solid 10 seconds or so. I suppose you could turn the air pressure down on your compressor and it would probably pull more slowly. I left my compressor at 90-100 PSI and nothing blew up. I did all 4 corners of my car in less than a half hour. It took longer to get each corner of the car off the ground, the wheel off, and the frame on a jackstand than it did to get the air out of the line. Brake stuff now doesn't seem like a big chore to me and I'm glad I can do it myself whenever I need to!

Bought it to not have to have a buddy come over and pump the brakes on my car.Setup was easy, although I did add teflon tape to the hose attachment threads for good measure as there was none.Once in place I set my compressor to the specified pressure, hooked up the provided hose, cracked the bleeder and pulled fluid quickly.As you can meter out exactly how much you want to pull it reduces wasted brake fluid.I did experience a mediocre deal around the rubber attachment, but as long as you keep pulling a vacuum before closing the bleeder it works fine.My only issue was that it consumes a lot of air, and I had to recharge my 3 gallon compressor several times to finish all 4 wheels. Not particularly the fault of this vacuum bleeder but just an observation.Also worked a treat for my motorcycle. As it has far less plumbing than my car, I was able to finish that in a matter of minutes and am a happy camper.It’s built with very thick plastic, seems to be very stout and well made. The activation lever is easy to engage and meter the vacuum you desire.The drain port at the top was an added bonus as you can just pop the cap off and pour what you extracted quickly for disposal.Overall very satisfied with this purchase.

Just used this Capri Vacuum Brake Bleeder to change the brake fluid in my Toyota Prius. It worked well doing this job. You just apply suction with the tool at each bleeder screw on the calipers to suck fluid through from the master cylinder. When the new fluid appears at the tool suction hose, you close the screw, and that line is done. Do the same for each.Each wheel only took a few minutes. I've done this job numerous times with a hand operated unit - it does the same thing, but it's messier, takes longer, and is hard on your hand. This vacuum bleeder makes the job much nicer - should have bought it years ago.Some reviewers have said that a large compressor is need to make the tool work. I used a 1 hp, 2.4 cfm@90psi , 4 gal unit that worked just fine for the job. Maybe a more powerful compressor would've made the job a little faster, but you don't absolutely need one.Also, some reviewers have mentioned that there was a lot of air in the suction lines, that they thought was air from the brake system - it's not - it's likely from around the loose threads of the bleeder screw. No need to worry about it, as the tool is pulling new fluid through the lines from the master cylinder. When I was done my job, the brakes still worked fine.When the job was done, the unit was only about half full of old fluid, so no need to dump it until the job is finished. Then, you just pull out the metal cap from the top of the unit and dump the old fluid.The unit seems like its made fairly decent too - it doesn't feel cheap and flimsy. The quick connect air supply line and suction fittings work well. Silicone suction tube is much better than cheap plastic tube.Conclusion: Great tool for replacing or bleeding brakes.

Great for brake fluid or sucking oil out of small engines etc. Works well. Would buy again

Significantly better value then snap on or Mac grade tools and works better. This unit is rugged and built very well. I spent $250 on a Mac bleeder tool that fell 2 feet and blew into 6 pieces voiding the warranty right away. My mistake yes, but with this tool if it falls you don't need to worry, and in a shop environment chances are this will take a tumble once in its lifespan. Nice design with the cap that comes off to empty it, keeps the entire tool much cleaner and stops the seals from being strained from constant opening and closing of the lid. 10/10 tool. (Only gripe would be included a slightly longer hose but 3.5 feet works pretty perfect for me.)

The unit is very rugged and works exactly as expected and desired, BUT, the only reason I did not give it 5 stars when it should have received 6 was because it comes with only 3' of hose when it should have at least 6'. This is just unbelievably DUMB as you cannot set the unit on the ground and then get the hose suction end close to where it needs to go, such as the master cylinder reservoir on a pickup truck or say a motorcycle. Instead you have to balance it on top of a pail or a ladder which is a BIG pain with a disaster waiting to happen if a spill occurs. Dumb, dumb, dumb, but hey, they saved on $1 worth of hose. The hose is 4mmx8mm and needs to be heavy wall to work under vacuum. After looking I was able to buy 15' for under $20 on Amazon but why should I have to do this? Why should you have to do this? I would still buy this unit as it is that good, but be prepared to go shopping for hose if you want it to be stable when being used and truly functional. Just mentally add $15 to the price and the value of your time to deal with this fixable deficiency. I guess we will see if the seller posts a notice that they will be addressing this defect?

I had a chance to use this many DIY projects and it worked perfectly every time. No complaints.
